Love Unanswered

Love is supposed to be grand. Why is it always considered a good and bad thing? Why do we want love so much? Love is perceived to offer us care, affection, comfort, understanding. Yet, it is so hard to obtain. Why? Why is it hard for people to love and even harder to allow themselves to be loved? How do we fix it? Is it internal? If we are to change ourselves to allow love in, how are we supposed to know what to change if we don't know what true love feels like? Why so many questions? Who has the answers?
I guess there is no definite answer. Love is not science. What do you say love is?
Love is felt. It's forgiveness. It's strength. Love is what I feel when I read your words and hear your heart as you introduce us to you, the real you.
